A long-term safety study was conducted with astaxanthin derived from Haematococcus pluvialis algae extract. Fifteen healthy volunteers took 9 mg of astaxanthin daily for 12 weeks. Physiological (including doctor’s consultation), haematological, biochemical, and urinary markers were examined at weeks 0, 4, 8 and 12. No adverse effects or clinical changes were observed throughout the test period. It was concluded that a healthy adult can consume 9 mg of astaxanthin derived from Haematococcus pluvialis algae extract for 12 weeks without any safety concern.

Annual changes in age, age at onset, incidence of cases with steroiddependent intractable asthma, clinical asthma types and clinical efficacy rate were examined in 256 patients with chronic respiratory diseases, especially in 203 cases with bronchial asthma, admitted to Misasa Branch Hospital from 1982 to 1989.
1. A number of patients with respiratory diseases as well as asthmatics admitted each year, having spa therapy, increased from early year (1982) to later year (1989).
2. A number in cases with 40 year or over of age (also with 60 year or over of age) and cases with 40 year or over of age at onset showed a tendency to increase in later three years (1987-1989). A decreased frequency of cases with steroid-dependent asthma and of cases with type II (bronchiolar obstruction type) was observed in the later three years.
3. The clinical efficacy of spa therapy for bronchial asthma was Niger in the later three years than in early three years (1982-1984).

Methods:
We reviewed 125 patients (79 men and 46 women) who had lumbar spinous process splitting laminectomy (LSPSL) for LSS. We assessed the following clinical information: Japanese Orthopedic Association (JOA) score; numerical rating scale (NRS) for low back pain (LBP), leg pain, and leg numbness; Zurich Claudication Questionnaire; JOA Back Pain Evaluation Questionnaire; Roland- Morris Disability Questionnaire (RMDQ); and Short Form 8 (SF-8) as HRQOL. We compared the HRQOLs of men and women pre- and postoperatively.
Results:
Although the preoperative NRS results for LBP were significantly higher in women (p <0.05), there were no significant differences in clinical outcomes between men and women postoperatively. For HRQOL, the RMDQ scores were significantly worse in women preoperatively (p <0.05), but no significant differences were found postoperatively between men and women. Similarly, the SF-8 mental health score was also significantly lower in women preoperatively (p <0.05), but no significant differences were noted between the two groups postoperatively.
Conclusions
LSPSL greatly reduced LBP, leg pain, and leg numbness in both genders. There were limited differences in pain and several HRQOL questionnaire responses between men and women after surgery. We found that women had greater sensitivity to and/or lower tolerance for pain than men, which led to lower HRQOL mental health scores preoperatively.

Objective:
There is no consensus on whether platinum doublet chemotherapy or lenvatinib and pembrolizumab (LEN/PEM) is superior for advanced or recurrent endometrial cancer. Thus, this study aimed to compare the prognosis and adverse events in patients with advanced or recurrent endometrial cancer treated with platinum doublet chemotherapy or LEN/PEM.
Methods:
We retrospectively reviewed the medical records of patients who received platinum doublet chemotherapy or LEN/PEM at our institution for advanced or recurrent endometrial cancer and had a history of platinum-based chemotherapy between January 2013 and August 2023.
Results:
During the study period, 11 regimens were identified in the platinum doublet chemotherapy group, and 11 regimens were identified in the LEN/PEM group. The objective response rates of the platinum doublet chemotherapy and LEN/ PEM groups were 36.4% and 54.5% (P=0.67), respectively. The 6-month progression-free survival (PFS) rates of the platinum doublet chemotherapy and LEN/PEM groups were 27.3% (95% confidence interval [CI], 13.8%-40.7%) and 70.0% (95% CI, 55.5%-84.5%), respectively. The differences were significant between the two groups. Multivariate analyses of histology, prior lines of chemotherapy, platinum-free intervals, and regimens revealed that the LEN/PEM group had significantly better PFS rates.
Conclusion
Treatment with LEN/PEM resulted in significantly longer PFS than that of treatment with platinum doublet chemotherapy in patients with advanced and recurrent endometrial cancer. However, further large-scale studies are required to validate these findings.

Surgery for an atrioventricular septal defect (AVSD) is rare in septuagenarians. This is the case of a 75-year-old man with partial AVSD. He developed dyspnea on exertion. Detail examinations revealed partial AVSD, severe left atrioventricular valve (LAVV) regurgitation, severe right atrioventricular valve (RAVV) regurgitation, persistent atrial fibrillation, and coronary artery stenosis, which required surgical intervention. Subsequently, we performed ostium primum-type atrial septal defect closure using an autologous pericardium patch, LAVV replacement with a bioprosthetic valve, RAVV repair without annuloplasty, a modified Maze IV procedure, left atrial appendage closure, and coronary artery bypass grafting. Although LAVV repair for LAVV regurgitation was initially performed, it was converted to LAVV replacement because the repair could not control the regurgitation due to advanced degenerative changes with the thickening of the leaflets. The patient was discharged on the 15th postoperative day uneventfully. One and a half years after surgery, he had neither cardiovascular events nor arrhythmias.
